2022-10-31Merge branch '2022-10-31-vbe-implement-the-full-firmware-flow'Tom Rini
To quote Simon: This series provides an implementation of VBE from TPL through to U-Boot proper, using VBE to load the relevant firmware stages. It buils a single image.bin file containing all the phases: TPL - initial phase, loads VPL using binman symbols VPL - main firmware phase, loads SPL using VBE parameters SPL - loads U-Boot proper using VBE parameters U-Boot - final firmware phase, where OS booting is processed This series does not include the OS-booting phase. That will be the subject of a future series. The implementation is entirely handled by sandbox. It should be possible to enable this on a real board without much effort, but that is also the subject of a future series.
2022-10-31vbe: Add a test for the VBE flow into U-Boot properSimon Glass
Add a test which checks that VBE boots correctly from TPL through to U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Add a command to show the VBE stateSimon Glass
Add a VBE comment which shows the current state. Currently this is just the phases which booted via VBE. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Record which phases loaded using VBESimon Glass
We expect VPL and SPL to load using VBE. Add a record of this so we can check it in U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Use a manual testSimon Glass
Use a manual test for the VBE test, so we can make the pytest and the C unit test work together properly. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vpl: Allow signature verificationSimon Glass
Add the required Kconfig option so that signatures can be verified when loading a configuration. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31sandbox: Add an image for VPLSimon Glass
Use binman to build an image which includes all the U-Boot phases so that a full VBE boot can take place with just that image.bin file. Attach the image file to mmc2 so it can be loaded. VBE is used to load images in two phases: - In VPL, VBE decides which SPL image to load - In SPL, VBE decides which U-Boot image to load The latter should really be determined by VPL, since it does the full signature verification on the selected configuration. However, we have separate configurations for SPL and U-Boot proper, so for now we keep it simple and have SPL do its own verification. This will need to be tidied up later. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Add info about the VBE device to the fwupd nodeSimon Glass
At present we put the driver in the /chosen node in U-Boot. This is a bit strange, since U-Boot doesn't normally use that node itself. It is better to put it under the bootstd node. To make this work we need to copy create the node under /chosen when fixing up the device tree. Copy over all the properties so that fwupd knows what to do. Update the sandbox device tree accordingly. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Add Kconfig options for VPLSimon Glass
Enable the various features needed in VPL, by adding Kconfig options. Update the defconfig for sandbox_vpl so that the build for each phase includes what is needed. Drop LZMA for now and make sure partition support is omitted in SPL, since it is not needed. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Drop the U-Boot prefix from the versionSimon Glass
We don't need the U-Boot prefix on the version and in fact it is harmful since pytest gets confused seeing the U-Boot banner bring displayed when the version is printed. Drop the prefix from the string. We could produce an entirely new string from the component parts, but this adds to the rodata size and would break the use of version_string as the only thing which holds this information. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Move OS implementation into a separate fileSimon Glass
Move this into its own file so it can be built only by U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Support reading the next SPL phase via VBESimon Glass
Add an SPL loader to obtain the next-phase binary from a FIT provided by the VBE driver. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Support selecting operations by SPL phaseSimon Glass
VBE supports booting firmware during the SPL phases, i.e. so that VPL can start SPL and SPL can start U-Boot. It also supports booting an OS, when in U-Boot. As a first step towards these features, add functions to indicate the current VBE phase. The firmware selection is done in VPL and the OS selection is done in U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31sandbox: Support obtaining the next phase from an imageSimon Glass
At present sandbox runs the next phase from discrete executables, so for example u-boot-tpl runs u-boot-vpl to get to the next phase. In some cases the phases are all built into a single firmware image, as is done for real boards. Add support for this to sandbox. Make it higher priority so that it takes precedence over the existing method. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31spl: Allow multiple loaders of the same timeSimon Glass
At present we only support a single loader of each time. Extra ones are ignored. This means that only one BOOT_DEVICE_BOARD can be used in the SPL image. This is inconvenient since we sometimes want to provide several board-specific drivers, albeit at different priorties. Add support for this. This should have no functional change for existing boards. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Use a warning for a failed requestsSimon Glass
Optional requests should present a warning rather than an error. Update the log call. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31vbe: Rename vbe_fixup to vbe_requestSimon Glass
The vbe_fixup file handles device tree fixups, but these are called OS requests in VBE. Rename the file to reflect its wider purpose. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31image: Allow loading a FIT image for a particular phaseSimon Glass
Add support for filtering out FIT images by phase. Rather than adding yet another argument to this already overloaded function, use a composite value, where the phase is only added in if needed. The FIT config is still selected (and verified) as normal, but the images are selected based on the phase. Tests for this come in a little later, as part of the updated VPL test. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31image: Add the concept of a phase to FITSimon Glass
We want to be able to mark an image as related to a phase, so we can easily load all the images for SPL or for U-Boot proper. Add this to the FIT specification, along with some access functions. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31sandbox: Add a way to specify the sandbox executableSimon Glass
At present the sandbox executable is assumed to be arg[0] but this only works for a single jump (e.g. from SPL to U-Boot). Add a new arg to solve this issue, along with a detailed comment. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31sandbox: Generalise SPL bootingSimon Glass
At present sandbox only supports jumping to a file, to get to the next U-Boot phase. We want to support other methods, so update the code to use an enum for the method. Also use the Use board_boot_order() to set the order, so we can add more options. Also add the MMC methods into the BOOT_DEVICE enum so that booting from MMC can be supported. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31image: Move comment for fit_conf_find_compat()Simon Glass
Move this comment to the header file, where the APIs should be defined. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31sandbox: Drop message about writing sandbox stateSimon Glass
This happens every time sandbox moves to the next phase so is not very interesting. Display the message only when debugging. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2022-10-31dm: mmc: Allow sandbox emulator to build without writesSimon Glass
When MMC_WRITE is disabled this driver produced a build error. Fix this. Also update a comment while we are here. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com>
2022-10-31dm: blk: mmc: Tidy up some Makefile rules for SPLSimon Glass
Use the correct SPL_TPL_ variable so that these features can be enabled in TPL and VPL as needed. Disable it by default in TPL to avoid any code-size increase. No boards are actually using it since the Makefile rules don't allow including drivers/block/ with TPL_DM enabled. It can be manually enabled as needed.

2022-10-31usb: Update the test to cover reading and writingSimon Glass
Add test coverage for blk_write() as well. The blk_erase() is not tested for now as the USB stor interface does not support erase. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31dm: blk: Add udevice functionsSimon Glass
At present we have functions called blk_dread(), etc., which take a struct blk_desc * to refer to the block device. Add some functions which use udevice instead, since this is more in keeping with how driver model is supposed to work. Update one of the tests to use this. Note that it would be nice to update the functions in disk-uclass.c to use these new functions. However they are not quite the same. For example, disk_blk_read() adds the partition offset to 'start' when calling the cache read/fill functions, but does not with part_blk_read(), which does the addition itself. So as designed the code is duplicated. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31disk: Rename block_dev to descSimon Glass
The use of 'block_dev' in this context is confusing, since it is not a pointer to a device, just to some information about it. Rename this to 'desc', as is more commonly used, since it is a block descriptor. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Heinrich Schuchardt <xypron.glplk@gmx.de>
2022-10-31disk: Rename block functionsSimon Glass
Use the uclass type as the first part of the function name, to be consistent with the methods in other block drivers. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31bootstd: Add a way to set up a bootflowSimon Glass
Add a function to init a bootflow, to reduce code duplication. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31test: Support tests which can only be run manuallySimon Glass
At present we normally write tests either in Python or in C. But most Python tests end up doing a lot of checks which would be better done in C. Checks done in C are orders of magnitude faster and it is possible to get full access to U-Boot's internal workings, rather than just relying on the command line. The model is to have a Python test set up some things and then use C code (in a unit test) to check that they were done correctly. But we don't want those checks to happen as part of normal test running, since each C unit tests is dependent on the associate Python tests, so cannot run without it. To acheive this, add a new UT_TESTF_MANUAL flag to use with the C 'check' tests, so that they can be skipped by default when the 'ut' command is used. Require that tests have a name ending with '_norun', so that pytest knows to skip them. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31test: Update tests to use the skip featureSimon Glass
Some tests currently return 0 when they want to be skipped. Update them to return -EAGAIN instead, so they are counted as skipped. A few tests are in two parts, with the latter part being skipped in certain situations. Split these into two and use the correct condition for the second part. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31test: Report skippped testsSimon Glass
At present it is possible for a test to skip itself by returning -EAGAIN but this is not recorded. An existing example is in test_pre_run() with the "Console recording disabled" check. Keep a track of skipped tests and report the total at the end. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2022-10-31binman: Support writing symbols into ELF filesSimon Glass
In some cases the ELF version of SPL builds may be packaged, rather than a binary .bin file. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31binman: Handle writing ELF symbols in the Entry classSimon Glass
This feature is used by several etypes and we plan to add more that use it. Make symbol writing a feature of the base class to reduce the code duplication. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31binman: Split out looking up a symbol into a functionSimon Glass
Move this code into its own function so it can be used from tests. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31binman: Allow obtaining a symbol valueSimon Glass
Provide a function to obtain the integer value of an ELF symbol. This will be used Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31spl: Add a separate silence option for SPLSimon Glass
Add an option to allow silent console to be controlled separately in SPL, so that boot progress can be shown. Disable it by default for sandbox since it is useful to see what is going on there. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31spl: Refactor controls for console outputSimon Glass
The expression in boot_from_devices() is fairly long and appears to be an artefact from before we could easily call printf(...) and have the call be nop'd out. So update it to just check CONFIG_SILENT_CONSOLE. Signed-off-by: Simon Glass <sjg@chromium.org> Suggested-by: Tom Rini <trini@konsulko.com>
2022-10-31spl: Use binman suffix allow symbols of any SPL etypeSimon Glass
At present we use symbols for the u-boot-spl entry, but this is not always what we want. For example, sandbox actually jumps to a u-boot-spl-elf entry, since sandbox executables are ELF files. We already handle this with U-Boot by using the '-any' suffix. Add it for SPL as well. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31disk: Drop debug messages in part_efiSimon Glass
This is monstrously verbose when something goes wrong. It should work by recording the problem and reporting it (once) at the command level. At present it sometimes outputs hundreds of lines of CRC mismatches. For now, just silence it all.
